# Active debris removal of approximately 60 large objects per year represents a scenario-dependent threshold for negative LEO debris growth, but current ADR capacity of 1-2 objects per year creates a 30-60x scale-up gap that is primarily a market structure problem, not an engineering problem

A 2026 peer-reviewed study in Frontiers in Space Technologies identifies removal of approximately 60 large objects (>10 cm) per year as the threshold at which debris growth in the 500-600 km LEO band becomes negative under current FCC 5-year deorbit rules. The paper explicitly notes this threshold is 'scenario-dependent' and 'not meant to be universal' — more complex fragmentation cascades would increase the required removal rate. Current ADR industry capacity stands at 1-2 objects per year (ClearSpace and Astroscale combined), creating a 30-60x gap between required and achieved removal rates. At $50-100M per ADR mission, achieving 60 removals per year would require $3-6B annually — equal to the entire projected 2034 ADR market size ($5.8B) in a single year. The gap is not primarily technical: 60 distinct removal missions per year is physically achievable. The binding constraint is the market structure, where ADR is government-funded rather than operator-funded, creating a commons tragedy in the cleanup market itself. Operators bear private launch profits while taxpayers fund externalized cleanup costs, violating Ostrom's proportional cost-benefit allocation principle for commons governance.
